As evidence, it points to the 2010 Tijuana arrest of Hezbollah
militant Jameel Nasr, who was allegedly tasked with
establishing a Hezbollah network in Mexico and South America.
The memo also recalls the April 2009 arrest of Jamal Yousef in
New York, which exposed a huge cache of assault rifles, hand
grenades, explosives and anti-tank munitions. According to
Yousef, the weapons were stored in Mexico after being smuggled
from Iraq by members of Hezbollah.

The memo warns that consequences of partnerships between
Hezbollah and Mexico's drug partnerships could be disastrous for
Mexico's drug war, given Hezbollah's advanced weapons
capabilities — specifically their expertise with improvised
explosive devices (IEDs). It notes that some Mexican criminal
organizations have
started using small IEDs and car bombs, a marked change in
tactics that indicates a relationship with Islamic militants.

Partnerships between Mexican organized crime and Islamic
militants are mutually beneficial — and therefore terrifying. The
cartels are able to gain smuggling and weapons expertise, as well
as access to cheap heroin from Afghanistan and Iran. The
terrorists benefit from Mexico's drug war lawlessness and its
porous border with their primary target: The United States.
